Mr Storrs, of Conn, says 4000 ; Mr Tufts, of Dudley, 

 3000 ; Mr D'Hornergue says 2400, of 350 to a pound, 

 the moth not stifled. 



I should say the last estimate was the most correct, 

 and even a less number will produce a pound if they 

 are well taken care of. I have had three pounds from 

 8000 in one season including floss. 



WEIGHT OF COCOONS. 



Two hundred cocoons, from worms raised in the ear- 

 ly settlement of Georgia, weighed a pound. In Penn- 

 sylvania, 306 cocoons from worms fed by the late Mr 

 Busti, and from 490 to 600 in the establishment of Mr 

 Terhoven, weighed a pound.* 



It is very evident that there is a great difference in 

 the weight as well as the quality of cocoons; and the 

 quantity required to make a pound of reeled silk. This 

 may depend upon the different variety of the worms or 

 the greater or less care in nursing them. 



*Mr Pintard of Philadelphia, has raised Silk Worms from eggs pro- 

 duced on Messrs Terhovens' farm, 335 of the cocoons of those 

 worms, chrysales not killed, weighed one pound. Mr D'Homer- 

 gue aided him in counting and weighing them. 



Of the cocoons raised in Philadelphia by Mr D'Homergue the 

 present year, which 1 saw, the eggs were partly from South Caro- 

 lina and partly from France ; the former were large and were found 

 when weighed, to contain 337 to a pound. The French cocoons 

 were small, ami 387 weighed one pound. The chrysalis not stifled 

 and the cocoons just gathered. 



Of cocoons raised in Massachusetts, by Mrs Davenport o Milton, 

 frorn eggs furnished by me, and tended agreeably to my instruc- 

 tions, 206 weighed one pound, before the chrysales were killed, 

 and 407 weighed two pounds.
